Abstract

A method for state synchronization, performed by a first electronic apparatus, comprises the following steps. A first service state version identification (ID) is acquired from a local cache of the first electronic apparatus. Multiple second service state version IDs stored in local caches of second electronic apparatuses are acquired by querying the second electronic apparatuses. It is determined whether each second service state version ID is older than the first service state version ID. A forward update request is transmitted to at least one second electronic apparatus owning the older second service state version ID, enabling the second electronic apparatus owning the older second service state version ID to activate an upward check procedure to update the older second service state version ID.
